What features of the calculator?

WITH KALK.PRO you'll produce a full calculation of stairs with winder steps of 90 degrees. In addition, the automatically generated 3D model by using the obtained calculations. The three-dimensional model reflects the convenient/inconvenient passage, allowing you to assess possible risks. The output you are getting ready engineering drawings for the handwritten production.

With us you save money. Calculator stairs with zabezhnymi stages will produce accurate estimates of volume, number of steps, dimensions and materials of construction. You don't have to call an expert and pay for his services, or to contact the furniture company and to order the production of stairs.

Save time. Why do you need to spend time on complicated calculations, when there is a our calculator stairs? You will be asked to enter the dimensions and click "Calculate".
